Ah....the infamous "Burro Brand" sawhorses show their faces once again. That means the California boys are busy mixing resin....and it aint for surfboards.

Looks like the cats out of the bag. Thats Bigshrimpin's project so I'll let him do the posting on that one. I've been holding his pic's hostage.

71kidcasper- To answer your question I let the duratec set up till it is still a little tacky then start the lay up. Never worked with gel coat. MDF makes good one off mold material.

Strick, If I wanted to use MDF for one off molds does it need to be sealed or coated with something so that there isn't any problem with release.

RB - that's the MDF mold it's held together with epoxy and 1708 4" tape. The inside is all that matters. Seams are bondo and clay then the inside is coated with epoxy. The epoxy sinks into the MDF and dries hard. It needs to be sanded and coated again, waxed with part all or another mold release wax. Then you can layup the part.

This is treading on new ground for me . . . Chucks pretty much doin all the work and making me feel like I'm doing something to contribute (instead of just drinking beer).

The angles and the measurements were tricky. We drew the footprint on the back of chuck's 20sf to get the shape right. It's really going to look good when it's done.

I'm still at work now and I'll be here again sat/sun (my second 60+ hour work week in a row), so no worky on the bracket for me this weekend.
